Apparel Expander for Digital Garment Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothing sizing methods are inconsistent, unreliable, and fail to accurately convey information about fit due to variations in sizing across brands and lack of elasticity data, leading to increased costs and inconvenience for both consumers and vendors due to high return rates and inefficient fitting processes.
Innovation Solution
A system and method using an apparel expander with a fluid distribution unit and sensors to create a three-dimensional model of clothing, generating digital size information that includes elasticity data, allowing for accurate fit recommendations and reducing the need for physical try-ons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sizing methods are used, then clothing can be manufactured and sold through traditional channels, but sizing accuracy and fit reliability deteriorate due to brand variations and lack of standardization
Solution Approach 1:
The patent creates a digital 3D copy of the physical garment by scanning it with sensors while it is inflated to its final shape. This digital model captures precise dimensional data, elasticity characteristics, and fit properties, replacing unreliable conventional size labels with accurate digital representations that can be stored and compared against customer body scans.
Solution Approach 2:
The invention transforms the garment from a flat, compressed state during manufacturing and shipping to an inflated, three-dimensional state during scanning. This parameter change (from compressed to expanded volume) allows the garment to assume its final wearing shape, enabling accurate capture of fit characteristics including elasticity and drape that cannot be measured from flat-packaged clothing.
2Measurement precision
If physical try-on methods are used, then customers can assess fit accuracy, but costs and time increase due to fitting rooms, personnel, and return processing
Solution Approach 1:
The patent replaces the mechanical process of physical try-on with a digital comparison system. Customer body scans are digitally matched against the digital garment model, using algorithms to predict fit without requiring the customer to physically try on the item. This substitution eliminates the need for fitting rooms and in-person assessment while maintaining fit accuracy.
Solution Approach 2:
The system enables customers to perform fit assessment independently by scanning their own bodies and comparing them against available garments using the digital platform. This self-service capability eliminates the need for store personnel to assist with fitting and allows customers to evaluate multiple items remotely before purchase.
3Adaptability or versatility
If multiple physical garments are shipped for trial, then customers can evaluate fit options, but shipping costs and environmental impact increase
Solution Approach 1:
The system creates virtual representations of multiple garment options that can be digitally tried on and compared without physical shipment. Customers can evaluate various styles, sizes, and fits through digital visualization and comparison tools, eliminating the need to ship multiple physical items for trial purposes.
4Reliability
If clothing is held in inventory for trial periods, then customers can return items for fit assessment, but inventory turnover decreases and seasonal value is lost
Solution Approach 1:
The system performs fit assessment before purchase by digitally matching customer body scans with garment specifications. This preliminary evaluation ensures customers select the correct fit on first purchase, eliminating the need for return periods and preventing inventory from being tied up in trial arrangements. Garments can be quickly rotated through inventory without waiting for return windows.

AI summary
A novel and useful system and method for measuring an article of clothing (AOC) that may include one or more of an apparel expander (AE) having an expansion chamber configured to be inserted into a cavity of the AOC and to receive an operating fluid (OPF), a fluid distribution unit (FDU) coupled to the AE and configured to control a supply of the OPF to, or from, the apparel expander, a sensor configured to detect contours of the AE when at least a portion of the AE is situated within the cavity of the AOC and form corresponding sensor information, and a controller configured to control the FDU to supply the OPF to the AE to expand the AE when at least a portion of the AE is situated within the cavity of AOC, obtain the sensor information from the sensor, reconstruct a three-dimensional (3D) model of the AOC based upon the detected contours of the AE obtained from the sensor information, and form digital size information (DSI) including information related to the reconstructed three-dimensional model.
